November 30, 1927, Serial No. 236,750, and in Germany March 25, 1927 This invention relates to a process and apparatus for the production of multicolored decorations upon supports of print in the pasting of certain parts of the representation in the course of the normal printing operation colored pieces of paper, metal foil or the like on to the paper or the like which receives the impression which process consists in preparing said pieces of sheet by a gummmg or damping device and applying them by a feeding device to the support of print in the course of the normal printing operation, advantageously by the co-operation of the printing cylinder with the printing surface, so that the printing of the representation and its completion by the pasted on pieces take place simultaneously and whichapparatus 18 characterized by a gumming or damping clevice for the preparation of the sheet mate-- rial and by a feeding device for the application of the pieces of paper or the like, which devices are actuated by the co-operation of the printing cylinder with a yielding part of the printing surface.

The subject matter of the invention is illustrated in two constructional forms by way of example in the accompanying drawings Figs; 1 and 2 are sectional views and show in elevation and plan ail-apparatus in which the pieces of paper, metal foil or the like to be pasted on are stamped out of anintermittently moving web or length of the material, while Figs. 3 and 4 are also sectionalviews and show likewise in elevation and plan an apparatus'in which leaflets already cut to shape and ready gummed are taken from a pile.

Fig. 5 illustrates detail of the apparatus shown in Figs. 3 and 4.

In the constructional form shown in Figs. 1 and 2 the printing part 1 of the block is movable in the direction in which printing takes place i. e. at right angles to the plane to be printed and tends to be constantly pressed upwards by the springs 3. To the part 1 are rigidly attached the bearings for two drums 4: and 5. The web of paper, metal foil or the like drawn oil the drum 1 passes first through V a gumming apparatus 6 and then runs over rollers 7, 8 and '9. The stationary stamping and gears into a gear wheel 21 on the shaft 22 of the drum 5. On the shaft 22 is mounted a jaw clutch 23, theclutch' member 23 of which co-operates with a friction disc 24.

There is also mounted on this shaft a ratchet wheel with which a pawl 26 co-operates'.

If the movable part 1 of the block be depressed by the printing cylinder (not shown) 13, 4t and 5 together with the web A and its roller guide, and also the device 6 will move downwards. The punch or stamp 11 stamps a piece out of the web A and conveys this piece through the opening in the movable part of the block upwards, until the stampedout piece lies at the same height with the printing surface of the part 1, and is pasted to the paper or the like pressed against it by the printingcylin-der. The impression of the part 1 of the block and the pasting on of the stamped-out piece of paper, metal foil or the like, are therefore carried out simultaneously.

On the downward movement of the block 1 the link 13 carries the lever 16 with it and rocks it about the pivot 15' into the position shown by dot and dash lines in which the lever 16 bears against a stop 31. During this movement of the lever the finger or cam 18 slides along the web A without clamping it. The drum 5 does not rotate during the upward movement of the part 1 of the block, as

it is prevented from doing so by the ratchet mechanism 25', 26 and the two clutch members 23, 23 run idly over each other. The web A therefore is stationary during the stamping and sticking on operations.

WVhen the part 1 of the block moves up wards again the link 13 is carried with it and after passing through the slot 12 the lever 16 is returned to the drawn position.

At the same time the web'A is clamped between the lug 1 7 and the finger cream 18 and drawn off to a corresponding extent from the drum 4. By the cooperation of the rack 20 with the gear wheel 21 thedrum will be simultaneously rotated by means of V 5: the clutch 23, 23', as the ratchet mechanism 25, 26 permitsof movement in this direction, and thereby the corresponding part of the web A is wound up on this drum. v

In the constructional form shown the drums 4 and 5 and also the gumming appa- "ratus 6 will be placed in the block itself. These parts may however also be placed outside the block. In like manner the drums 4 and 5 and the gummingapparatus 6 may be arranged underneath the block.

In the constructional form shown in Figs. 3 to 5, the colored pieces of paper, metal foil and the like are taken from a pile which is placed inside a block with a movable print- I 9 mg surface- 32 denotes the pile from which each separate sheet is taken by means of an arm 33 and supplied to a standard 34. This arm 33 carries on one end a plate 35 of felt or the like whichis kept constantly moist 25 by the'arrangement-shown in Fig. 5. The

end of the 'arm 33 engages with a nut 36 which surrounds a portion 37 which is guided in a bearing 38 fixed to the part 1. y

. To the movable part ispivoted av lever, 39

which is connected to the underside of a bellows 40. From this latter a pipe 41 leads under the upper end of thestandard 34 and on the underside of the bellows 40 is pro-' vided avalve 42, which ,can'co-operate with 35. a fixed stop 43. A two-armed lever controlled by a spring 44 serves always to keep the pile adjusted to the height of the top sheet. p 1 Q SL812 it be assumed thata leaflet to be pasted on is already on the standard34. \Vhen the movable part 1 of the block descends, the arm 33'will first be rocked by the co-operation of 36 with 37, in such away that it and the plate 35 will pass out of the path of the 45 standard 34 above the pile 32. On the fur- V ther downward'movement of'the part 1 of the block the arm 33 willnow move parallel to itself downwards and touchthe topmost sheet .of the ile 32 with its moistened plate 35 The lea ets ofthe pile- 32 are gummed on their uppersides. As soon as the part 1 of the .block has moved so far downwards that its u per side lies at the same height as the lea et lying on the standard 34, this 5 leaflet will be pasted by the pressure of the printing roller to the paper receiving the impression; During the descent of the part '1 the bellows 40' is extended by means of the I lever 39 so that in it and in the pipe 41 and 5 also below the leaflet lying on the standard a vacuum will be created, which will hold the leaflet securely on the standard. When the part 1 has reached its lowermost position, the valve 42 strikes against the stop 43 and 5 is opened thereby, so that air can pass into the bellows and the vacuum previously exist-.

'ing therein is again destroyed. This is the instant when the sticking on of the leaflet lying on the standard takes place, at which instant the leaflet consequently is no longer under the action of the vacuum in the bellows 40. a r

On the withdrawal of the part 1 of the 7 block, the arm 33 moves with the leaflet adhering to the felt plate 35 parallel with itself upwards. Towards the end of the upward movement the nut 36" again engages with the screw threaded part 37 and is thereby again rotated into position above the standard 34.

' The bellows 40 is at the same time again com- 7 pressed bythe lever 37 and 011 thenext' descent of t is again explained, whereby. the leaflet is suckedagainst the standard and securely held thereon, while the arm 33 with its ring 35 is swung away from the standard towards the pile 32 andithe above cycle of operations is repeated.

In order always tokeep the feltplate 35 moist, a water reservoir 46with a spring controlled piston 47 is provided (Fig. From this reservoir branches off a capillary tube 48. At an opening 49in this tube a drop of water forms, past ,which the felt late 35 moves eachtimethe arm 33 is roe ed and takes up the drop formed.

e part 1 of the block the bellows;

. The arrangement described may. be used in all kinds'of ways. Thus for example in-, stead of one pile, several piles maybe placed ing an opening extending therethrough at' rightangles to the printing surface anda punching plunger in register with the said opening, means for effecting a vertical motion of the said printingblock, and means for obtaining printed illustrations or designs over the upper surface of the said punching plunger.

2. In combination, a printing block carrying an opening extendlng therethrough at right angles to the printingsurface and a punching plunger in register with the said opening, means for effecting vertical motion of the said printing block, means for passing a web of printed illustrations or designs over the upper surface of the said plunger, and :means for applying a layer of adhesive to the under surface of the said web. r V

' 3. In combination, a printing block carrying an, opening extending therethrough at right angles to the printing surface, a plunger in register with the said opening, a standard adapted toreceive a stack of printed illustrations or designs, means for transporting a printed illustration from the said stack to the said plunger and Vacuum means cooperating with the said plunger whereby the said printed illustration or design is caused to adhere to the said plunger.

4. The process of simultaneously printing and aifixing a painted illustration to a sheet of paper, cloth or the like which comprises aflixing a printed illustration or design 35 gummed on its reverse side, and which reverse side has been moistened shortly before its aifixation to the said sheet, by pressing thesaid illustration or design against the said sheet by appropriate means and simultane- 2 ously printing the said sheet by other means cooperating with the first named means, which impress an inked printing form at the appropriate portion of the said sheet.
